-' My invention relates to effervescent compounds such as baldng powder, leavening preparations, or powders designed to afiect the palatability,-taste or solubility ofmedicinal or other compounds, and the object of the invention is to provide an improved,

simple and efiicient compound of this, character which will be noninjurious and which 6 maybe produced at a low cost.

My improved compound is amixture of sodium becarbonate and sodium pyrosulfate,

the chemical reaction of which when brought :in contact with water or other suitable menf ties.

struum or solvent, produces sodium sulfate, water and carbon dioxid. The sodium sulfate produced by this reaction is a neutral saline substance without injurious proper- The mixture of sodium bicarbonate and sodium pyrosulfate may be used as an effervescent preparation to secure the evolution of carbon dioxid for leavening preparations. It may also be used to prepare efi'er- Wvescent powders and preparations to aflz'ect the palatability, taste or'solubility of medic {in'al or other compounds.

Application filed September 9, 1915. Serial No. 49,827. A

One ounce of a mixture of 168 parts sodium bicarbonate and 222 parts sodium py- 'rosulfate will, in contact with water, gen-' erate about twenty-three one-hundredth 1 40 ounces of carbon dioxid, equivalent to about one-ninth of a cubic foot, if measured under standard conditions. In certain circumstances it may be advisable or convenient to increase the bulk of the-material or owder by adding a suitable filler, as of ome formof sugar,vstarch or other well known and harmless substance.

, Manifestly other pyrosulfates, such as the sodium acid pyrosulfates or the potassium 5o.

pyrosulfates or mixtures ofsuch pyrosulfates, may be used instead of the sodium 3. As an article-of manufacture,an eifer- 65 vescent preparation "containing a 'sodlum pyrosulfate.

In testimony whereof, I have signed this specification. V
